PERLEY L. KIMBALL, OF BELLOVVS FALLS, VERMONT, ASSIGNOR TO THE VERMONT FARM MACHINE COMPANY, OF BELLOWS FALLS, VERMONT,

A CORPORATION OF VERMONT.

CENTRIFUGAL SEPARATOR.

SPECIFICATION formingpart of Letters Patent No. 751,178, dated February 2, 1904:.

Application filed Apri12 2, 1901- To all whom it may concern.-

Be it known that I, PERLEY L. KIMBALL, a citizen of the United States of America, residing at Bellows Falls, in the county of I/Vind- 5 ham and State of Vermont, have invented a certain new and useful Improvement in Oentrifugal Separators, of which the following is a description, reference being had to the accompanying drawings, wherein- Figure 1 is a view in central vertical section of an apparatus embodying said improvement. Fig. 2 is a side elevation of the partition, approximately cylindrical inform, which is carried within the separator-drum. Fig. 3 is a view of an apparatus embodying said improvement in horizontal cross-section on the plane denoted by as looking downward. Fig. i is a perspective view of a liner made according to my invention. Fig. 5 is a plan view of the top of the device, showing the outlets.

The object of the improvement is the production of an apparatus for separating mixed liquids of diiferent densities, notably for separating cream from new milk.

The apparatus will herein be described as applliied to the separation of cream from new 1111 In the accompanying drawings, the letter (0 denotes a separator-drum which in use and practice rotates very swiftly, some six or seven thousand turns a minute. I

The letter Z) denotes the cover of the separator-drum. Its lower part is conical and its upper part cylindrical. When the apparatus is in use, the drum is secured to the cover by the ring-nut 0.

The letter (Z denotes packing, of rubber or the like, which may be cemented to the drumcover for making the joint tight between the drum and the cover. In order to hold the drum and the cover stationary each with the other while the ring-nut is being screwed into place or removed therefrom, the cover is provided with a tenon b, which fits into a corresponding mortise in the interior wall of the separator-drum.

The letter 6 denotes a thimble which is fastened into the upper end or neck of the cream- .the milk-tube, it being their function to aid in Serial No. 56,853. (No model.)

disk. It is pierced centrally by an inlet for full milk and non-centrally for the adjustable cream-outlet f.

The letter g denotes what may be termed the cream-disk. It, like the cover, is conical in its lower part and cylindrical in its upper part. It fits within the cover. It is supported at the top of the cover and maintained in a central position by the spacing-blocks 9 The wings g are for the purpose of causing the milk to rotate with the bowl. The creamdisk g may rest upon the upper end of the separator-drum, or it may be separated therefrom a short distance, as shown in Fig. 1 of the drawings. This disk g catches the cream as it rises and practically conducts it to the adjustable cream-outlet. The skim-milk rising on the interior. wall of the drum passes over the top of the cream-disk and out through the adjustable skim-milk outlets h.

The letter i denotes a milk-tube, which at the upper end communicates with the fullmilk inlet in the thimble 6. This milk-tube extends to near the bottom of the separatordrum and there delivers the full milk below the plate k. This plate A; has perforations is, through which the milk rises to begin the process of separating the cream from the milk. This plate A; extends to practicalcontact with the interior of the separator-drum, not, however, making an absolutely tight joint therewith. On its under side the plate k carries supports K, which rest on the floor of the separator-drum and raise the plate A: a little above the same.

The letter Z denotes radial wings carried by 5 making the milk take the rotation of the Whole apparatus.

The letter m denotes as a whole and in a general sense a partition which is as a whole approximately cylindrical in form. It rests on the plate in. It is provided with passages 01. to permit the outward movement of the milk and the inward movement of the cream. These passages are arranged spirally from top to bottom of the partition and are bounded by plates which are integrally united one with the other,

floor of the separator-drum, passes into a corresponding mortise in the plate k and so aids in making that plate rotate in unison with the.

separator-drum. The contact of the lips m with the interior wall of the separator-drum helps the cylinder m to rotate in unison with the separator-drum.

In the practical use of this device the full milk enters the full-milk inlet, passes down the milk-tube and out at the lower end thereof, and rises through the perforations in the plate It, thus reaching the interior of the partition m. The swift rotation of the whole apparatus tends to make the cream seek the center, and the more watery portions, known as blue milk, seek the walls of the separatordrum. The peculiar formation of the cylinder m, already described, facilitates the separation of the cream from the blue milk. The cream, seeking the center, readily flows through the passages n, on the inner side thereof, at the same time that the blue milk flows outwardly through the same passages, at the outer side thereof. The cream, which accumulates in the center, rises against the creamdisk and passes out of the apparatus through the adjustable cream-outlet. The blue milk,

which has reached the wall of the separatordrum, rises and passes over the outside of the cream-disk and through the adjustable skimmilk outlets.

It Will be observed that the use of an adjustable cream-outlet and also an adjustable skimmilk outlet doubles orduplicates the possibilities of adjusting the device to its work. i

I claim as my improvement 1. In combination the separator-drum, the drum-cover having a conical lower part and cylindrical upper part, the cream-disk held within the drumcover and having conical lower part and cylindrical upper part, the thimble in the upper end of the cream-disk pierced bythe central inlet for full milk, and a vertically-arranged adjustable outlet for the cream, substantially as described and for the purposes set forth.

2. In a separator the drum, the drum-cover having a lower conical part and upper cylindrical part, the cream-disk held within the drum-cover and having a conical lower part and a cylindrical upper part, the thimble in the upper end of the cream-disk pierced by a central inlet for milk and a vertically-arranged adjustableoutlet for cream, in combiof the drum-cover, substantially as described,

and for the purposes set forth.

3. In combination; the separator-drum, the

drum-cover, the thimble in the upper end of the cream-disk pierced by central inlet for full milk and non-central outlet for cream, the milk-tube communicating with the central inlet for full milk and extending to near the bottom of the drum and adapted to deliver milk below the plate next mentioned, the plate duly supported near the bottom of the drum, extending to contact with the interior wall of the drum, and perforated by milk-orifices, and a partition approximately cylindrical in form supported on said plate, all substantially as described and for the purposes set forth.

4:. A liner having a multiplicity of slots therethrough, the walls of which are arranged angularly with respect to the wall of the liner and thus give direction to the slots across the radial lines from the axis of the liner.

5; A liner substantially cylindrical in form having a multiplicity of slots therethrough, the bounding-walls of said slots being bent at an angle to the liner-wall, thus directing the fluid moving in the passages formed by said slots across the radial lines of the liner.

6. A liner substantially cylindrical in form having a multiplicity of slots therethrough, the bounding-walls of said slots being arranged angularly with respect to the liner-wall, the outer edges of said bounding-walls being bent outwardly to form lips.

7. Aliner substantially cylindrical in form having a multiplicity of vertical slots therethrough, the bounding-walls of said slots being bent out of the tangential plane of the linerwall, thus directing the fluid movingin the passages formed by said slots across the radial lines of the liner.

8. A liner substantially cylindrical in form having a multiplicity of slots therethrough, the bounding-walls of said slots being arranged angularly with respect to the liner-wall, thus directing the fluid moving in the passages formed by said slots across the radial lines of the liner, and grooves formed in the boundingwalls of the slots.

9. A liner substantially cylindrical in form having a multiplicity of slots therethrough, the bounding-walls of said slots being arranged angularly with respect to the liner-wall, thus directing the fluid moving in the passages formed by said slots across the radial lines of the liner, and lengthwise grooves formed in the bounding-walls of the slots.

10. A liner substantially cylindrical in form having a series of circumferential rows of slots therethrough, the bounding-walls of said slots being arranged angularly with respect to the liner-wall, the slots in one row being staggered with respect to those in the next adjacent row.

11. A liner substantially cylindrical in form having a series of circumferential rows of vertical slots therethrough, the bounding-Walls of said slots being bent out of the tangential plane 5 of the liner-Wall, the slots in one roW being staggered With respect to those in the next adjacent row.

12. A liner substantially cylindrical in form having a series of circumferential rows of vertical slots therethrough, the bounding-Walls I of said slots being bent out of the tangential plane of the liner-wall, the slots in one roW overlapping those in the adjacent rows, and being staggered With respect thereto.
